Its not a wax in the tradition sense as in a carnauba wax, it has got waxes in it I believe but its basically a sealant.
The Super Resin Polish is a cleaner polish and slight sealant so topping it with the Ultra Gloss Protection (think its called Extra Gloss Protection to) will be perfect because it is a sealant with no cleaning abilities so you are just adding a (more if you want to) layer of extra protection. You can then if you want top the UGP with a proper wax if you want to maybe change the look eg wetter look or better reflections depending on what you use.
There might be someone along that knows more about the AG stuff as I don’t tend to use it myself, more of a Klasse/Carlack68 or poorboys fan for my sealants, but hopefully the above helps a bit.
